The specific embodiment

Below, cyclone dust-separating apparatus among the present invention is described with reference to the accompanying drawings in further detail

Embodiment.

Fig. 1 has described the vacuum cleaner 10 that adopts cyclone dust-separating apparatus 100 according to an illustrative embodiment of the invention.Vacuum cleaner 10 comprises dust catcher body 11, extension 12, flexible hose 13 (shown in the dotted line), by extension 12 and the absorbent brush 14 that flexible hose 13 is connected with dust catcher body 11, removably be fixed on dust catcher body 11 forward spin flow dust-separating appliances 100.

The front that connecting hole 11b is formed at dust catcher body 11 is connected to suck part 117a fluid with the air of cyclone dust-separating apparatus 100.In vacuum cleaner 10 assembling processes, flexible hose 13 is inserted among the connecting hole 11b.

Dust catcher body 11 is provided with dirt collecting chamber 11a, and wherein cyclone dust-separating apparatus 100 places dirt collecting chamber 11a.Dust catcher body 11 also is provided with air exhaust filtering net 15, and in the time of in being in dirt collecting chamber 11a, cyclone dust-separating apparatus 100 is placed on the air exhaust filtering net 15.The air discharge ports 112a (see figure 4) of cyclone dust-separating apparatus 100 is communicated with the suction power source (not shown) fluid that is positioned at dust catcher body 11 by air exhaust filtering net 15.

With reference to Fig. 2, cyclone dust-separating apparatus 100 comprises rotary fluid 110, and loam cake 120 and backflow prevent projection 130.

Rotary fluid 110 is cylindrical container of a dirt collecting chamber S2 who has the S1 of spin chamber that forms in inside center and form along periphery.Therefore, rotary fluid 110 comprises outer wall 111, bottom surface 112 (see figure 4)s and inwall 113.

With reference to Fig. 3 and Fig. 4, the S of spin chamber 1 is formed jointly by inwall 113 and bottom surface 112, and dust " X " is separated from the inhaled air among the S1 of spin chamber eccentrically.The height H 2 of inwall 113 is lower than the height H 1 of outer wall 111, highly is the interface channel P of H4 to form.With shown in the chain-dotted line, interface channel P is the space that forms between inwall 113 and loam cake 112 as Fig. 4.

Guide S11 is positioned on the bottom surface 112 of the S1 of spin chamber.Guide S11 is along encapsulate air delivery pipe 115 on the hand of spiral, so that its height 112 rises to height H 6 from the bottom surface.Because the existence of guide S11, the air that is full of dust that sucks from air intake pipe 117 can keep its vortical force, thereby is imported in the loam cake 120.In the another one embodiment, the bottom surface of guide S11 and rotary fluid 110 112 whole formation, if necessary, guide S11 also can with rotary fluid 110 in make independently, weld then or stick on the bottom surface 112.

With reference to Fig. 3, air intake pipe 117 is placed on the lower position of rotary fluid 110, and runs through outer wall 111 and inwall 113.In addition, as shown in Figure 5, air intake pipe 117 is positioned at the end of the S1 of spin chamber, thereby provides centrifugal force to the air that is full of dust, and air intake pipe can be taked different shapes such as rectangle or triangle.The air that is full of dust that is inhaled into by air inhalation part 117a and air inflow pipe 117 is imported among the S1 of spin chamber.

With reference to Fig. 4, air discharge ports 112a is positioned at the center of the bottom surface 112 of the S1 of spin chamber, and it is soldered and stick on the air discharge ports 112a to have the air discharge pipe 115 of predetermined altitude H5.

The height H 5 scheduled air that are full of dust that suck from air inflow pipe 117 with assurance of air discharge pipe 115 are not directly discharged but discharging smoothly after being filtered.According to test, the height H 5 of air discharge pipe 115 obtains by following formula:

Formula: H5=H6+ (H2-H6) * 1/3

That is to say, the height H 2 of inwall 113 deduct guide S11 height H 6 obtained on duty with 1/3.Then, the height H 6 of guide S11 adds that height (H2-H6) * 1/3 obtains the preferred heights H5 of air discharge pipe 115.It is 1/3 that the coefficient that is multiplied by does not limit, and also can be the number between 1/3 to 1/2.

Air discharge pipe 115 can be by bottom surface 112 whole formation of die casting and the S1 of spin chamber, and it can have different shapes, for example circle, rectangle and triangle.The air that is separated dust by air discharge ports 112a and air discharge pipe 115 emits from cyclone dust-separating apparatus 100 along arrow F2 direction.

With reference to Fig. 4 and Fig. 5, dirt collecting chamber S2 is the space that is enclosed in the S1 of spin chamber periphery, and it is used for dust X is collected within it.Thus, dirt collecting chamber S2 is surrounded by inwall 113, outer wall 111 and bottom surface 112 and forms.

As mentioned above, S1 of spin chamber and dirt collecting chamber S2 are by separated from one another, and dust-separating X carries out with the different space that operates in of collecting dust X from inhaled air.Correspondingly, as shown in Figure 7, when vacuum cleaner 10 was reversed, dust X was splashed on the lower surface of loam cake 120, was collected in that dust X is not back among the S1 of spin chamber among the dirt collecting chamber S2.Like this, dust X has been prevented from four times dispersions.

Because air inhalation part 117a and air discharge ports 112a are installed on the outer wall 111 and bottom surface 112 of rotary fluid 110, so the structure of loam cake 120 also is simplified separately.

When vacuum cleaner 10 was reversed, the dust that is kept among the S1 of spin chamber was prevented from being discharged among the air discharge ports 112a by air discharge pipe 115, and this is because air discharge pipe 115 is positioned on the bottom surface 112 (that is, a side) relative with loam cake 120.

To Fig. 6, shape is similar to the upper part that round loam cake 120 covers rotary fluid 110 with reference to Fig. 4.The upper part that covers rotary fluid 110 up to loam cake just can form interface channel P.

In the another one embodiment, a lid (not indicating) replaces loam cake 120 to be connected with the upper part of outer wall 111, and this lid is not movable, and it is used to cover the upper part of rotary fluid 110.In this case, the dust that is collected in the dirt collecting chamber S2 is discharged from by opening with closable bottom surface 112.

Shape is similar to backflow cylindraceous and prevents that projection 130 is outstanding from the lower side 102a of loam cake 120, and a part of blocking interface channel P.Backflow prevents that the height H 3 of projection 130 is lower than the height H 4 of interface channel P, and refluxing like this prevents projection 130 partial occlusion interface channel P, thereby forms the accessory channel P1 of an annular.

In the S1 of spin chamber, dropped onto among the dirt collecting chamber S2 by accessory channel P1 by the dust X of centrifugation.For ease of reference, in Fig. 4, represent the space that forms by accessory channel P1 with chain-dotted line.

Backflow prevents that projection 130 has the inside diameter D 2 bigger than the internal diameter of spin chamber S1.Correspondingly, the dust X that centrifugation has gone out from inhaled air prevents that with backflow projection 130 from colliding in the direction of arrow A, then by accessory channel P1 vertically just the arrow C direction drop onto among dirt collecting chamber S2 rather than the S1 of spin chamber.

In addition, the air stream that carries dust X prevents that along arrow A direction and backflow projection 130 from colliding, and then, vertically just the arrow C direction sinks among dirt collecting chamber S2 rather than the S1 of spin chamber.So as shown in Figure 7, when vacuum cleaner 10 was reversed in clean operation, the vertical air flow resistance that descends had hindered the dust X that is collected among the dirt collecting chamber S2 to be back among the S1 of spin chamber.

In addition, the dust that is collected also can be prevented from four times to be disperseed.That is to say, be collected in dust X among the dirt collecting chamber S2 and float to loam cake 120 on attempting, but because the air that vertically descends stream and can not floating, thereby turn back among the dirt collecting chamber S2.Dust X and air stream fall simultaneously or sequentially.

Further, shown in Figure 7, when vacuum cleaner 10 is reversed, at first, because S1 of spin chamber and dirt collecting chamber S2 are separate, so the dust X that is collected among the dirt collecting chamber S2 is back among the S1 of spin chamber by obstruction in first operation; Secondly, prevent from backflow in second operation, also can hinder dust and be back among the S1 of spin chamber under the effect of the vertical decline air stream that projection 130 forms by accessory channel P1.

Because air discharge pipe 115 is positioned on the bottom surface 112, when vacuum cleaner is reversed, is kept at the interior dust of the S1 of spin chamber and is prevented from being discharged among the air discharge ports 112a by delivery pipe 115.

Hereinafter, the operation that description is had the cyclone dust-separating apparatus 100 of said structure.

With reference to Fig. 1, when vacuum cleaner 10 was driven, dust was sucked from the surface that is cleaned by absorbent brush 14 by the suction that is produced by suction power source (not shown).The dust X that is inhaled into is by extension 12, and flexible hose 13 and the air inhalation part 117a that is communicated with the connecting hole 11b fluid of dust catcher body 11 enter cyclone dust-separating apparatus along arrow F1 direction.

With reference to Fig. 3, the dust X that is inhaled into flow among the S1 of spin chamber by air inflow pipe 117.At this moment, because air inflow pipe 117 is positioned at a side of the bottom surface 112 of the S1 of spin chamber, centrifugal force is added on the dust X.And owing to guide S11 places on the bottom surface 112 of the S1 of spin chamber, and along hand of spiral encirclement air discharge pipe 115 and rising highly gradually, dust keeps centrifugal force, and is introduced in the loam cake 120.

With reference to Fig. 4, dust X is centrifuged among the S1 of spin chamber by said process, and moves up along interface channel P.Then, dust X moves along the arrow A direction, prevents projection 130 collision with backflow, and then the accessory channel P1 that also is vertical direction by interface channel P along the arrow C direction drops onto among the dirt collecting chamber S2.Alternately, dust X does not prevent projection 130 collisions with backflow, but directly the accessory channel P1 by interface channel P drops onto among the dirt collecting chamber S2.

Simultaneously and/or sequentially, the air stream with dust-separating X prevents that along arrow A direction and backflow projection 130 from colliding, and then the accessory channel P1 that is vertical direction by interface channel P along the arrow C direction drops onto among the dirt collecting chamber S2.The dust that decline air stream prevents to be collected among the dirt collecting chamber S2 rises.

Then, air after the filtration discharges from cyclone dust-separating apparatus 100 along arrow F2 direction by air discharge pipe 115 and air discharge ports 112a, then emits from vacuum cleaner 10 (see figure 1)s by air exhaust filtering net 15 (see figure 1)s and suction power source (not shown).

According to the embodiment of the present invention, the advantage of cyclone dust-separating apparatus 100 is as described below.

At first, refluxing prevents that projection 130, the S1 of spin chamber and dirt collecting chamber S2 from being separated from one another, thereby has stoped the dust X that is collected in dirt collecting chamber S2 to splash and be back among the S1 of spin chamber.Correspondingly, can prevent that also air exhaust filtering net 15 from being filled up by dust X.

Secondly, because air discharge pipe 115 is positioned on the bottom surface 112, when vacuum cleaner 10 was reversed, the dust that is kept among the S1 of spin chamber was prevented from being discharged among the air discharge ports 112a by air discharge pipe 115.Correspondingly, when vacuum cleaner 10 is reversed, also can stop air exhaust filtering net 15 to be filled up by dust.

The 3rd, because air inhalation part 117a is positioned on the outer wall 111 of rotary fluid 110 and air discharge ports 115 is positioned on the bottom surface 112, the structure of loam cake is simplified.Like this, the dust of collection can just be moved out of by simply opening loam cake.

At aforesaid embodiment and advantage only is exemplary, and can not be interpreted as a kind of restriction of the present invention.Above-mentioned only is illustrative to explanation of the present invention, and can not be construed as limiting the scope of this claim to those skilled in the art, obviously can make variously substituting, improving and change the present invention.In the claims, the functional specification statement is intended to cover all structures of the function that can realize its statement, not only comprises structural equivalent, and comprises equivalent configurations.
